Patented Aug. 19, 1941 HINGE CONSTRUCTION FOR UPWARD ACTING DOORS Henry J. Siess, Detroit, Mich., assignor to Crawford Door Company, Detroit,lMich., a corporation of Michigan Application September 9, 1940, Serial No. 355,892

7 Claims.

This invention relates to a hinge construction especially adapted for connecting the sections or panels of a sectional type upward acting door.

More specifically the invention relates to a hinge construction having separable mating parts which can be mounted on the door panels or sections at the factory and interlocked on the job by means of a door roller to provide an articulated door.

This application is a continuation in part of my copending application, U. S. Serial No. 334,- 720, entitled: Door construction, filed May 13, 1940.

While the invention will be hereinafter specifically described in connection with an upward acting garage door of the sectional type, it should be understood that the hinges of this invention are adapted for general usage in connecting pairs of movable members in articulate relation. 7

According to the present invention there is provided a hinge construction having separate mating parts held in articulate relation by abutment between a flange on one of the parts and a hub of a roller disposed over a pin carried by another of the parts. The mating parts are quickly separated by removal of the roller from the pin. However, when the roller is on the pin,

the parts cannot be separated, but will be hingedly interlocked.

Each hinge part is composed of an angle plate or bracket having one leg thereof adapted to project over the side edge of a door panel or section and the other leg thereof projecting over the inner face of the door section or panel. This other leg is readily secured to the inner face of the door panel by means of screws or bolts and the hinge parts can be mounted on their respective door panels without ever assembling the panels in articulate relation. Then when the panels are being installed to build up a finished garage door unit, the mating hinge parts already mounted on the panels are quickly brought into interlocking articulate relation by means of the door rollers which serve to mount the door in a doorway.

It is, then, an object of this invention to provide a hinge construction including separable mating parts held together in articulate relation by means of a sleeve disposed over one of the parts.

A further object of the invention is to provide a door hinge having readily disengageable interlocking parts held together. by cooperation between a flange on one of the parts and a detachable sleeve on another of the parts.

A specificic object of this invention is to provide a hinge construction for upward acting garge doors of the sectional type which makes use of a door roller to hold the hinge parts in articulate relation.

A further specific object of this invention is to provide a hinge construction for sectional type upward acting doors which construction includes disengageable hinge parts secured to the inner faces of adjoining door sections and extending over the edges of said section with one of the parts projecting through the other of the parts and forming a support for a door roller which locks against a flange carried by said other part.

Other and further objects of the invention will be apparent to those skilled in the art from the following detailed description of the annexed sheet of drawings which discloses a preferred embodiment of the invention.

On the drawing:

Figure 1 is a side elevational view of a pair of door sections or panels held together in articulate relation by a hinge construction according to this invention and illustrating in dotted lines the angular movements permitted between the door sections by the hinge construction.

Figure 2 is a fragmentary inside plan view taken along the line II-II of Figure 1.

Figure 3 is a fragmentary exploded side elevational view of the mating hinge parts.

Figure 4 is an exploded inside elevational view taken along the line IVIV of Figure 3.

Figure 5 is a bottom plan view taken along the line VV of Figure 2 with parts illustrated in horizontal cross section.

Figure 6 is a vertical cross-sectional view of the adjoining edges of the door panels taken along the line VI--VI of Figure 2.

As shown on the drawing:

In Figures 1, 2 and 6 the reference numerals I6 and H designate adjoining sections or panels of a sectional type upward acting garage door. As best shown in Figure 6, the panel It has a rounded groove or recess Illa in the bottom edge thereof bounded by a long leg or finger 19b at the front face of the door and a short leg or finger lllc at the rear face of the door. The top edge of the door section I I has a bead I la fitting into the groove Illa and bounded on the front side thereof by a horizontal shoulder l lb adapted to abut against the bottom of the leg 10b and a vertical shoulder Hc adapted to abut against the inner face of the leg Illc. The inner face of the panel II is beveled inwardly as at (Z to the vertical shoulder He.

The door panels Ill and II are thus adapted to tilt relative to each other while being held throughout their length by the interfitting groove and bead construction.

According to this invention the door panels I I] and I I are held in articulate relation by means of mating hinge parts I2 and I3 as shown in.

Figures 1 to 5.

The hinge part I2 comprises an angle plate or bracket having one leg or flange I2a extending over the side edge of the. doorsectionlll and the other leg or flange lzb ext'ending over the inner face of the door panel Iii. The flange I2!) is apertured to receive screws or bolts I4 therethrough for uniting the bracket integrally with the panel I0.

The flange I2a on the side edge of the panel has a dependent offset apertured portion I5'extending below the legs I221 and- I2b in spaced lateral relation from the side edge ofthe panel [0. The bottom of the offset portion I5 overlaps the'top of the panel portion II.

The bottom end of the portion I5'i's bifurcated providing an open bottomed recess I6 bounded byfingers or furcations Iiia and Ifib. The blind endof the recess is is semi-circular as at IEa (Figure 3) while the sides of the recesses defined by the inner edges of the fingers Ida and I5b slope along straight lines toward the inner face of the door. The free bottom end of the finger I51) is bent along a sloping line I50 extending diagonally across the full width of the finger to provide an outturned flange I? of triangular shape withthe apex Ila thereof aligned with the bottomof the recess it. Thus the flange H extends from the mouth of the recess along a sloping line to the outer edge of the offset portion I5.

The hinge part I3 comprises an angle plate having one leg or flange I 3a thereof extending ger -'37 on ball bearings 22 around a hub 23. The hub 23 projects beyond the tread portion 2| and its ure 1.

over the side edge of the panel II and the other leg or flange I3b thereof extending over the inner face of the panel II. The leg I3b is apertured and bolts or screws such as I4 extend through the apertures for uniting the plate to the inner face of the door panel II.

The hinge part I3 has a free end portion I8 projecting'upwardly from the leg I3a and flush with the leg. A cylindrical pin I9 projects 1aterally from one face of the free end portion I8 and is integrally-united to the portion I8. The pin I9 is-sized so that it can freely fit into the recess I6. 1 V

When it is desired to join'the door panels III and II- in articulate relation the same are mounted to move the bead IIa of the section I I into the recess IGa of the section If] and to move the offset portion I5'of the hinge part I2 into overlapping relation with the portion I8 of the hinge parti3 as shown in Figures 1 and 2. The portion I5 is offset from the door edges just sufliciently so that the portion I8 can extend into the'space provided between the door edge and the portion I5.

The pin I9, as explained above, will fit freely through the open'mouth'ofthe recess "5- and, being cylindrica1,.wi1l ride against the blind end IBaof the recess. 3 V

Aioloor roller 20. is provided for. mounting the door sections Ill and II in theusual track providedfonupward actingdoors; The roller 2'0 comprises a tread portion 2| rotatably mounted The;flange therefore thrusts against the hub and prevents removal of the pin I9 out of the recess.-

The flange I 'I can ride over the hub as indicated in dotted lines in Figure 1 to permit articulatemovement of the door sections. How ever; any movement 'of'thej' door sections tending to separate'the hinge? parts is resisted by the flange.

The hub of the roller 2U therefore acts as. a

lockingsleeve which c'onnectsthe" hinge parts I2.

and I3 together'for articulate movement;

Thus; acc'ordin-g tothis invention, door panels or door sections" can" be. equipped with hinge hardware and shipped in separatedcondition with the hardware thereon. The panels are readily mounted into. articulate relation for providing a.sectional type door when the door rollers are slid in' position on the pin'mounting provided by the hinges.

The'door" r'ollers of course operate. in the usual guiding'tracks'provided in upward acting door constructions;

f It will, of"course,.be understood that various details of "construction may bevaried through a wide range Without departing from the prin ciples of this invention and it is, therefore; not the'purpdseto limit the patent granted hereon otherwise than necessitated'by the scope'ofthe' appendedblaims.
